This can help to avoid DoS attacks. I would love to see that to get my
key down to a reasonable size.
OpenPGP specifies Key Server Preferences (18.104.22.168) with just one flag:
First octet: 0x80 = No-modify the key holder requests that this key
only be modified or updated by the key holder or an administrator of
the key server.
By default GnuPG sets this flag but unfortunately it has no effect
because it is not defined on how the keyserver can check this condition.
A way to implement this without requiring an external protocol would be
an extension to OpenPGP to either allow an Embedded Signature (22.214.171.124)
in a key signature. With ECC this would not increase the size of a key
signature too much. It puts a burden on the keyservers to check this
signature during an upload, though.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
